Description
Technical field
This utility model relates to harmonic speed reducer field, refers in particular to a kind of harmonic speed reducer four spot contact bearings.
Background technology
Under the powerful promotion of modern economy, bearing industry has come into a brand-new high-quality fast-developing period, and bearing has become a kind of very important parts in plant equipment in the present age.Nowadays, robot the most constantly develops rapidly, needs among these to use substantial amounts of bearing, and its major function is to support machinery selective body, in order to reduce the mechanical load coefficient of friction loseed in transmission process.In robot key components and parts, harmonic speed reducer serves the effect of key, in miniaturization harmonic wave field, can not be with traditional decussation bearing, but need the bearing of smallerization to substitute, therefore, this is made further research by the present inventor, developing a kind of harmonic speed reducer four spot contact bearings, this case thus produces.
Utility model content
The features such as the purpose of this utility model is to provide a kind of harmonic speed reducer four spot contact bearings, has volume little, lightweight.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of harmonic speed reducer four spot contact bearings, including inner ring, outer ring, ball, described ball is arranged between the track of inner ring and the track of outer ring, and described outer ring is combined by outer ring one and outer ring two, and the track of described outer ring is divided into two by outer ring one and outer ring two.
Further, described outer ring and described inner ring all offer connecting hole.
Further, it is provided with oil sealing between described inner ring and outer ring.
Further, the contact angle of described four spot contact bearings is 35-45 degree.
Further, the contact angle of described four spot contact bearings is 40 degree.
After using such scheme, this utility model compared with prior art, has the advantage that
Increasing the axial bearing capacity of bearing, volume is little, lightweight, stable drive, noise are little, it is possible to be applicable to light-type harmonic speed reducer.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model；
Label declaration
Inner ring 1, outer ring 1, outer ring 23, ball 4, oil sealing 5, connecting hole 6.
Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
As shown in the figure, a kind of harmonic speed reducer four spot contact bearings, including inner ring 1, outer ring, ball 4(steel ball), ball 4 is arranged between track and the track of outer ring of inner ring 1, and outer ring is combined by outer ring 1 and outer ring 22, and the track of outer ring is divided into two by outer ring 1 and outer ring 22, owing to outer ring is separable, so without the pattern using steel ball press-loading, more ball 4 therefore can be loaded, can be effectively improved the bearing capacity of bearing.
Screwing through hole (both connecting hole 6) is preset in outer ring, it is simple to install with harmonic speed reducer housing,
Inner ring 1 track is relative with outer race track, and inner ring 1 is installed by screw with flexbile gear as the outfan of harmonic speed reducer, the screwing through hole of inner ring 1.
Oil sealing 5 is arranged on the left side of four spot contact bearings, prevents leakage of oil and dust, it is ensured that the sealing of whole product.
The contact angle of four spot contact bearings is 40 degree, and contact angle is the biggest, and the axial bearing capacity of bearing is the highest, can compare favourably with angular contact bearing.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design that this utility model carries out unsubstantiality, the behavior invading this utility model protection domain all should be belonged to.
